HINGE AND FASTENING OF WINDOW-IBLINDS.

Specification of Letters Patent No. 5,683, dated August 1, 1848.

To all whom it may concern:

Be it known that I, CHENEY REED, of

Cambridge, in the county of Middlesex and State of Massachusetts, haveinvented new and useful Improvements in the Mode of Hanging andFastening Blinds, and that the following description, taken inconnection with the accompanying drawings, hereinafter referred to,forms a full and exact specification of `the same, wherein I have setforth the nature and principles of my said improvements, by which myinvention may be distinguished from others of a similar class, togetherwith such parts or combinations as I claim and desire to have secured tome by Letters Patent.

The figures of the accompanying plate of drawings represent myimprovements.

Figure l is an elevation of the exterior of a window frame with blindsarranged thereon according to my improved mode, one blind being shut andthe other open. Fig. 2 is an elevation of the interior of the same. Fig.3 is a horizontal section taken in the plane of the line A B, Figs. land 2. Fig. 4 is a detail vertical section taken in the plane of theline C-D, Fig. 3, and Fig. 5 is a det-ail transverse vertical sectiontaken in the plane of the line E-F, Fig. 3.

The blinds art-aa are of the ordinary kind and have let into theunderside of the bottom rail a small loose bolt bb, Fig. 1, which movesfreely up and down and engages with the slots in the catches c, c, onthe sill (l, Z of the window frame when the blinds are closed, and withsimilar slots in catches e, e, secured to the face of the building whent-he blinds are open. The sash ai, a', x, is represented as whole in theframe to show the effectual working of my apparatus.

In hanging blinds, it has long been desired by housewrights to devisesome means by which, when closed, they may be opened, and vice ver-sa,without opening the sash of the window, which in cold or stormy weatherinvolves considerable exposure on the part of the inmates of the house.Various plans or mechanical arrangements have been resorted to forsecuring the result above suggested, but the operation of all of themhas been very imperfect and ineifectual. By my improved arrangement theblinds may be easily opened and shut from the interior of the apartmentwithout opening the window, and the distinguishing feature of my saidarrangement consists in so supporting the blinds at the lower hinge onwhat I denominate a shifting or tilting or reversible circular inclinedplane that they may be raised on their bearings, and through the mediumof a friction roller (resting on said inclined plane, as explained inthe sequel) turn either way by their own weight. l

The upper hinges f, f may be of the ordinary construction and shaped asshown in Fig. 1, saving that the half of the hinge containing the stapeis attached to the blind, and that containing the socket to the windowframe instead of the opposite way, which is the usual plan. The samearrangement also exists in my improvements in the lower hinges g-L g-L,and the upper parts g-g, are made into hollow caps, so to speak, so asto protect the operative parts of the apparatus from rust, occasioned byrain, etc. The circular tilting planes are arranged between the twoparts g-/t of the lower hinges, as shown in figs. l, 4, and 5, and areattached to the ends of rods cc-s/c which extend through the windowframe into the interior of the apartment, as shown in Figs. 3 and 5,having knobs ZZ on their inner ends, by which the said inclined planesmay be turned from an angle of about 45 degrees (to the side of thewindow frame) in one direction, to a similar angle in the other oropposite direction. There is a hole in the tilting planes through whichthe staple of the lower hinge passes into the socket It, L and on thetop of this socket 7L the bearings of the said tilting planes rest andturn, as shown in Figs. 4 and 5. In the interior of each of the caps g-ga friction roller wwf-fm, is arranged, (see Figs. 3, 4, 5,) so as torevolve freely and run on the tilting planes and when said tiltingplanes are turned into the angular positions herein above described, (byapplying the hand to the knobs ZZ in the interior of the apartment,) thesaid rollers will run down said planes, and (being connected asdescribed to the caps g-g, an-d said caps being attached to the blinds aa) the said blinds will be carried by their own weight around onehundred and eighty degrees inv either direction as the case may require.When the wind is high the weight of the blinds may not be suiiicient tocarry them around, and I therefore apply an additional force on the topof the caps gg, by means of a spring frm, Figs. l and 5, (or anymechanical equivalents,) one end of which spring is fastened in whichthey are when the blinds are.

opened or shut it will be seen that the blinds cannot be lifted in theirbearings. The confinement of the said planes is effected by thefollowing arrangement of mechanical `de-I vices: A circular metalliccollar 79, p, Fig. 2, is fixed on each rod Icke/67a of said planes inthe interior of the apartment and' between the knobs Z Z and the insideof the window frame, as shown in Fig.l 5. In this collar two notches g--e], g--Q (shown by dotted lines in Fig. 2) are' formed at a properdistance from each other and into these notches, a sliding bolt w(moving up and down in grooves in the blocks s, 8') drops and t-s whenthe blinds are opened or closed, and in combination with the studs 00fasten the blinds in a manner which will be readily understood by whathas been said herein above.

It will be evident from inspection 0f the drawings that in lieu ofcombining the op- The improvement hereinabove described, v

in hanging blinds so that they may be opened or closed without raisingthe window viz., by supporting them on a tilting or reversible circularor other 'shaped inclined plane, fixed on the end of a turning rod, klc, said plane and rod being operated .or tilted from the interior ofthe apartment, substantially as hereinabove set forth, a friction rollerbeing connected to the blind as above set forth, an-d running on saidplane, as above explained. i

In testimony thatwthe foregoing is a true description of my saidimprovements and invention I have hereto set my signature thistwenty-sixth day of Jan., A. D. 1848.

CHENEY REED.
